Ultra-Compact SOT-23 Package Achieves 1.6μA Power Consumption, Enabling Battery Life Breakthroughs in TWS Earbuds and IoT Devices
Advanced sensor technology leader Sikor today announced the SL1603 Series, a new ultra-low-power Hall switch sensor. Featuring an industry-leading 1.6μA@1.8V standby current (5Hz version), omnipolar magnetic response, and dual-selectable thresholds (33G/46G), this solution delivers precision non-contact detection for space-constrained battery-powered devices. It boosts energy efficiency by 40% in TWS earbuds, smart locks, and other compact applications.
